					Flea-borne (murine) typhus was a nationally notifiable disease from 1930 until 1987.
During 1930 through the 1940s, thousands of cases of flea-borne typhus were reported annually. Beginning in the 1950s, cases of flea-borne typhus began to decline drastically, in part due to widespread advances in sanitation and pest management. By 1958, less than a hundred cases were reported each year.
Because of the rarity of the disease, in 1987, the Council of State and Territorial Epidemiologists voted to remove flea-borne typhus from the list of nationally notifiable diseases.
Flea-borne typhus cases still occur in certain areas of the country, including California, Hawaii, and Texas.
Reporting is still required in some states and local jurisdictions. Check with your state or local health departments to learn if flea-borne typhus is reportable in your state and, if applicable, what the current case counts are in your area.Number of Annual Typhus Group Rickettsiosis Cases, 1930-1987
